![]() I found the requestAnimationFrame() pattern to be much a more elegant solution than the setInterval() pattern. It is also compatible with many popular JavaScript libraries, including React and TypeScript. It can be used for front-end applications as well as for server-side programming. It works with both - Node.js and regular JavaScript. Optional Requirements:Īdditionally here is some light reading about the requestAnimationFrame() pattern: For instance, Moment is useful for data validation as well. requestAnimationFrame() – use this for animation rather than setInterval(). ![]() CountdownJS: (And Rawgit to be able to use countdownjs).Light reading about the requestAnimationFrame pattern: Var now = moment() // new Date().getTime() Note: 2nd line above updates as per momentjs and 3rd line above updates as per countdownjs and all of this is animated at about ~60FPS because of requestAnimationFrame()Īlternatively you can just look at this code snippet: Output: The time is now: 5:29:35 pm, a timer will go off in a minute at 5:30:35 pm ![]() $(".countdown").text(countdown(then).toString()) $(".difference > span").text(moment().to(then)) The Javascript: var now = moment() // new Date().getTime() The time is now:, a timer will go off at EasyTimer.js is a simple library for counting time in five different units: tenth of seconds, seconds, minutes, hours and days. But the time left is not coming as expected. I am calculating date difference between event date and current date (timestamp), then using 'duration' method from moment js. I created a demonstration here at codepen.io. I am making a countdown timer for an event page, i used moment js for this. Var duration = moment.duration(leftTime, 'seconds') Īlthough I’m sure this won’t be accepted as the answer to this very old question, I came here looking for a way to do this and this is how I solved the problem. Var leftTime = eventTime - currentTime //Now i am passing the left time from controller itself which handles timezone stuff (UTC), just to simply question i used harcoded values. This is a Moment.js plugin that allows the use of timers, which offer much more control than the native JavaScript timers. I read the momentjs documentation to figure out the problem, but no luck. This is a Moment.js plugin that allows the use of timers, which offer much more control than the native JavaScript timers. $('.countdown').text(moment(duration.asMilliseconds()).format('H:mm:ss')) Var duration = moment.duration(time*1000, 'milliseconds') ĭuration = moment.duration(duration.asMilliseconds() - interval, 'milliseconds') I am calculating date difference between event date and current date (timestamp), then using “duration” method from moment js. Moment-timer.js is freely distributable under the terms of the MIT license.I am making a countdown timer for an event page, i used moment js for this. If the changes make sense and the quality of code is good enough, then it will be merged into the master branch so other people can use it.Ī full list of contributers for moment-timer.js can be found here. Create your own branch, make the changes you wish to see and create a pull request that we can have a look at. The Moment library includes many other methods that are much more interesting. let momentObject moment() In this example, we return a simple moment object, representing the code’s execution time. You are always welcome to contribute to this repository. Let’s look at one example of using the Moment library in React. I am making a countdown timer for an event page, i used moment js for this. v1.1.0:Ĭhanged setDuration to duration and added actual moment.duration support to it.ĭeprecated error message on setDuration will be removed in next release. v1.1.1:Ĭleaned up some things, fixed a remainingDuration bug and added an internal clearTimer function. Fixing this will ensure that stopping and starting the timer will not cause any problems. It still had an old unused paused variable instead of the new stopped variable. v1.2.0Īdded getDuration and executeAfterWait attribute. Updated readme with better documentation and added a new isStarted function. ![]() If this function is called on a timer that has reached the end of it's duration and does not loop, it will also return false as if the timer has not yet been started.įeel free to open a new issue or create a pull request if you can think of other useful attributes or functions.įixed issue where. This function can be used to see if the timer has been started by the.
